This week Mr Slinger did not just take the lead role of Richard. He allowed
it to enter his very being so that his pale, imperfect body twitches like some
possessed Caribbean zombie.
In a performance that is at times disgusting to watch (yet gripping), the
shaven-headed Mr Slinger's body convulses with the ecstasy of the evil his
character is committing. Occasionally he jumps high in the air, like Sir Mick
Jagger celebrating a final chord. This is an amazing
performance.
